Description

Technical Field

[0001] This utility model relates to a transformer, specifically an amorphous alloy three-dimensional wound core transformer. Background Technology

[0002] Transformers are one of the fundamental pieces of equipment for power transmission and distribution, and new high-efficiency and energy-saving transformers are being vigorously developed. Amorphous alloy three-dimensional wound core transformers, as a typical example of new high-efficiency and energy-saving transformers, use iron-based amorphous metals for their cores, reducing unit iron loss by more than 50% compared to silicon steel transformers. This results in superior energy-saving and consumption-reducing effects compared to transformers with silicon steel cores. However, in related technologies, compared to silicon steel core products, amorphous alloy three-dimensional wound cores experience vibrations due to unstable operation, generating significant noise. This can easily affect surrounding residents, thus hindering the widespread adoption of amorphous alloy three-dimensional wound core transformers. Utility Model Content

[0003] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide an amorphous alloy three-dimensional wound core transformer, thereby reducing the noise generated during the operation of the amorphous alloy three-dimensional wound core.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an amorphous alloy three-dimensional wound core transformer includes an oil tank and a transformer body disposed within the oil tank. A first sound-absorbing component is fixedly disposed on the inner wall of the oil tank. The transformer body includes a shock-absorbing mechanism disposed on the bottom wall of the oil tank, a clamping frame mechanism fixedly disposed on the top of the shock-absorbing mechanism, a second sound-absorbing component fixedly disposed on the outer surface of the clamping frame mechanism, an amorphous alloy three-dimensional wound core disposed on the clamping frame mechanism via a pad mechanism, and a coil winding wound on the amorphous alloy three-dimensional wound core.

[0006] As a further limitation of this utility model, the pad block mechanism includes a lower pad block disposed between the top of the lower clamp and the bottom of the coil winding, an upper pad block disposed between the bottom of the upper clamp and the top of the coil winding, and three upper yoke pad blocks disposed between the top of the coil winding and the bottom of the three upper yokes in the amorphous alloy three-dimensional coil core.

[0007] As a further definition of this utility model, the lower pad includes three first corner pad units, six first side pad units, and one first middle pad unit. One first corner pad unit is provided at each of the three corners of the lower clamp and the bottom of the coil winding, two first side pad units are provided at each of the three sides of the lower clamp and the bottom of the coil winding, and one first middle pad unit is provided at the middle of the lower clamp and the bottom of the coil winding. Each of the first corner pad units, first side pad units, and first middle pad units is provided with multiple first pad guide grooves.

[0008] As a further definition of this utility model, the upper pad includes three second corner pad units, six second side pad units, and one second middle pad unit. A second corner pad unit is provided at each of the three corners of the upper clamping member between the top of the coil winding and the top of the coil winding. Two second side pad units are provided at each of the three sides of the upper clamping member between the top of the coil winding and the top of the coil winding. A second middle pad unit is provided at the position between the top of the coil winding and the middle of the amorphous alloy three-dimensional coil core. A pressure block is fixed on the top of the second middle pad unit. The second corner pad unit, the second side pad unit, and the second middle pad unit are all provided with multiple second pad guide grooves.

[0009] As a further definition of this utility model, the upper yoke pad includes an upper yoke pad unit and an upper yoke damping block fixed on the upper yoke pad unit, wherein the upper yoke pad unit is provided with a plurality of upper yoke pad guide grooves.

[0010] As another limitation of this utility model, the shock absorption mechanism includes a plurality of clamping frame shock absorption pads fixed to the bottom of the clamping frame mechanism. The clamping frame shock absorption pads include a clamping frame shock absorption pad body, a plurality of upper shock absorption protrusions fixed to the top surface of the clamping frame shock absorption pad body, and a plurality of lower shock absorption protrusions fixed to the bottom surface of the clamping frame shock absorption pad body.

[0011] As a further limitation of this utility model, the coil winding is provided with a plurality of insulating strips to form winding oil channels for the passage of insulating oil in the oil tank.

[0012] As a further limitation of this utility model, an epoxy resin insulating layer is fixed on the outer surface of the amorphous alloy three-dimensional coiled iron core.

[0013] As a further limitation of this utility model, the thickness of the epoxy resin insulating layer is 2mm to 3mm.

[0014] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0015] (1) This utility model adopts a structure in which the clamping frame mechanism and the pad block mechanism cooperate to fix the position of the amorphous alloy three-dimensional wound iron core and the coil winding. The fixing method is stable and can effectively reduce noise. The weight of the amorphous alloy three-dimensional wound iron core is supported by the clamping frame mechanism. The amorphous alloy three-dimensional wound iron core is suspended. The bottom of the amorphous alloy three-dimensional wound iron core does not directly contact the bottom of the oil tank. In actual use, the vibration force is transmitted to the shock absorption mechanism through the clamping frame mechanism, which can effectively reduce noise. At the same time, the generated noise needs to be transmitted to the outside through the first sound absorption component and the second sound absorption component, which can further effectively reduce noise. When using this utility model, it can effectively reduce the impact on the surrounding residents, which is conducive to the promotion and use of amorphous alloy three-dimensional wound iron core transformers.

[0016] (2) The clamping frame mechanism of this utility model includes a lower clamping member, an upper clamping member and multiple clamping screw components, and the pad block mechanism includes a lower pad block, an upper pad block and three upper iron yoke pad blocks. In actual use, the lower clamping member, the upper clamping member and multiple clamping screw components cooperate with each other to form a reliable clamping force. At the same time, through the action of the lower pad block, the upper pad block and the three upper iron yoke pad blocks, the position of the amorphous alloy three-dimensional coil core and the coil winding can be stably fixed, thereby effectively reducing noise.

[0017] (3) The present invention provides three first corner pad units, six first side pad units and one first middle pad unit at the position between the lower clamp and the bottom of the coil winding, three second corner pad units, six second side pad units and one second middle pad unit at the position between the upper clamp and the top of the coil winding, and three upper yoke pads between the top of the coil winding and the three upper yokes of the amorphous alloy three-dimensional coil core. Therefore, under the action of the clamping frame mechanism, the pad mechanism can fix the position of the amorphous alloy three-dimensional coil core and the coil winding at multiple positions, which can effectively reduce noise.

[0018] (4) The present invention is provided with a first pad block guide groove, a second pad block guide groove and an upper iron yoke pad block guide groove. When in use, the insulating oil in the oil tank can pass through the first pad block guide groove, the second pad block guide groove and the upper iron yoke pad block guide groove, which is conducive to heat circulation and heat dissipation, and can improve the heat dissipation effect of the present invention, thereby reducing the noise generated by the present invention due to thermal expansion and contraction.

[0019] (5) The shock absorption mechanism of this utility model has multiple upper shock absorption protrusions and multiple lower shock absorption protrusions. The multiple upper shock absorption protrusions and multiple lower shock absorption protrusions can form a small elastic unit, which can absorb vibration energy, enhance the damping effect, and thus reduce noise. In addition, the multiple lower shock absorption protrusions form a biting effect with the contact surface of the bottom wall of the oil tank, which increases the static friction force and prevents the clamping frame mechanism from sliding during vibration, which can effectively improve the reliability and stability of this utility model.

[0020] (6) The present invention has an epoxy resin insulating layer fixed on the outer surface of the amorphous alloy three-dimensional wound iron core, which can increase the overall structural rigidity of the amorphous alloy three-dimensional wound iron core and reduce the transmission of vibration energy, thus effectively reducing the noise during the use of the present invention.

[0021] In summary, this utility model employs a clamping frame mechanism and a padding block mechanism in combination to fix the position of the amorphous alloy three-dimensional wound core and the coil winding. The fixing method is stable, and the amorphous alloy three-dimensional wound core is suspended as a whole, with its bottom not directly contacting the bottom of the oil tank, thus preventing vibration energy from being directly transmitted to the oil tank and effectively reducing noise. Furthermore, this utility model also includes a shock-absorbing mechanism, a first sound-absorbing component, and a second sound-absorbing component, which can further effectively reduce noise. This utility model is suitable for use as basic equipment for power transmission and distribution. Attached Figure Description
